OpenIoT & ELC Europe 2016

Complex system-on-chip processors provide performance levels for their devices and peripherals. The same chips also provide interconnects with performance knobs connecting these devices. For years, Linux has not provided a way to express the relationship between a device and its performance states, nor a uniform method for drivers to change these states. There are many solutions to this in downstream vendor trees. Let's fix that.

The purpose of this BoF is to start a discussion around the topic with a wide audience, solicit feedback on the currently proposed approach and move forward with consensus.

This BoF will discuss the types of performance states that need to be modeled, existing Linux driver frameworks that can be re-used, new code that needs to be written and how Device Tree plays a role. Will we write a new DVFS or Interconnect Framework? Attend and find out!
